Hello,

I am encountering a strange problem. I wrote a very simple Processdefinition:

<?xml version="1.0" encoding="UTF-8"?>

<process-definition
 xmlns="" name="objectTest">
 <start-state name="start">
 <event type="node-leave">
 <action name="action1" class="com.test.SetUpActionHandler"/>
 </event>
 <transition name="" to="node1"></transition>
 </start-state>
 <end-state name="end">
 </end-state>
 <node name="node1">
 <action class="com.test.ObjectTestActionHandler" />
 <transition name="" to="end"></transition>
 </node>
</process-definition>

In the SepUpActionHandler class I declare a simple TestObject and put it into the ContextInstance:

package com.test;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

public class SetUpActionHandler implements ActionHandler {

 private static final long serialVersionUID = 1L;

 public void execute(ExecutionContext executionContext) throws Exception
 {
 TestObject to = new TestObject();
 to.setText("TestString");
 executionContext.getContextInstance().setVariable("Test", to);
 }
}

The TestObject itself is a very minimal serializable object:

package com.test;

import java.io.Serializable;

public class TestObject implements Serializable {

 private static final long serialVersionUID = 1L;

 private String _text = "leer";

 public TestObject()
 {

 }

 public String getText()
 {
 return _text;
 }

 public void setText(String s)
 {
 _text = s;
 }
}

And finally, in the ObjectTestActionHandler, I retrieve the TestObject from the ContextInstance:

package com.test;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

public class ObjectTestActionHandler implements ActionHandler {

 private static final long serialVersionUID = 1L;

 public void execute(ExecutionContext executionContext) throws Exception
 {
 Object o = executionContext.getContextInstance().getVariable("Test");
 TestObject to = (TestObject) o;

 executionContext.getToken().signal();
 }
}

When I execute this process in Eclipse, everything runs fine, there are no errors. But when I deploy it to a JBoss AS (4.0.4) and start it using the jbpm-web-console, I get a ClassCastException with the message: "com.test.TestObject cannot be cast to com.test.TestObject"

The Exception is thrown by the ObjectTestActionHandler in the line where the casting is done:

TestObject to = (TestObject) o;

Does anybody know why this happens?
